Title
(DE) VERFAHREN ZUR VERHINDERUNG VON ABLAGERUNGEN IN ENTWÄSSERUNGSSYSTEMEN
(EN) METHOD FOR PREVENTING DEPOSITS IN DRAINAGE SYSTEMS
(FR) PROCÉDÉ PERMETTANT D'ÉVITER LA FORMATION DE DÉPÔTS DANS DES SYSTÈMES DE DRAINAGE
Abstract
(DE) Beschrieben wird ein Verfahren zur Verhinderung von Ablagerungen in Entwässerungssystemen durch die Zugabe von geeigneten Mineralsalzen zum anfallenden Bergwasser. Durch die Zugabe kann die Bildung von Biofilmschichten reduziert oder eliminiert werden, die normalerweise bei den verschiedenen Verfahren zur Härtestabilisation entstehen. Durch die Zugabe der Mineralsalze können sowohl alte harte Ablagerungen wieder entfernt werden und gleichzeitig auch neue Ablagerungen verhindert werden. Des weiteren betrifft die vorliegende Erfindung Verwendung von Mineralsalzen zu solchen Zwecken sowie Depotsteine die einen wesentlichen Gehalt an solchen Mineralsalzen aufweisen.
(EN) Disclosed is a method for preventing deposits in drainage systems by adding suitable mineral salts to the accruing mountain water. This addition allows the formation of bio film layers, which normally form during various processes for stabilising hardness, to be reduced or eliminated. Adding the mineral salts allows both old, hard deposits to be removed and simultaneously prevents new deposits. The present invention further relates to the use of mineral salts for such purposes, and to depot stones with a substantial content of such mineral salts.
(FR) L'invention concerne un procédé permettant d'éviter la formation de dépôts dans des systèmes de drainage, en ajoutant des sels minéraux appropriés à l'eau d'infiltration souterraine. Ledit ajout permet de réduire ou empêcher la formation de couches de type biofilm alors que celles-ci se forment normalement lors de différents procédés visant à stabiliser la dureté. L'ajout desdits sels minéraux permet à la fois d'enlever d'anciens dépôts durs et, en même temps, d'éviter la formation de nouveaux dépôts. En outre, la présente invention concerne l'utilisation de sels minéraux à de telles fins ainsi que des réservoirs sous forme de blocs solides dont la teneur en de tels sels minéraux est considérable.
